[0029] The specific implementation method is as follows: when stirring is required, the air supply pipe of the refrigerator is connected to the connecting pipe 59, so that the cold air of the refrigerator is delivered to the refrigeration pipe 510, and then ejected through the jet port 511, and the first motor 52 is started, and the connecting shaft 55 is driven by the first motor 52, and the stirring blade 58 is driven by the connecting shaft 55, and the cement in the stirring shell 2 is stirred by the stirring blade 58.
